Introducció
The HIFIMAN HE-400I is a high-quality, full-size planar magnetic headphone designed for critical listening in home or studio environments. Weighing approximately 370 grams (13.1 ounces), it is significantly lighter than many comparable planar magnetic headphones, enhancing comfort during extended use. Key design elements include a newly developed headband and beveled hybrid ear pads, contributing to both comfort and acoustic performance. The headphones utilize single-ended drivers to deliver a lifelike soundstage and precise spatial imaging. With an efficiency of 93dB, the HE-400I can be powered by a modest amplifier or even portable audio players and smartphones. A premium cable, constructed from Crystalline metal with Oxygen-free copper and silver, is included. The ear cups feature an ABS polymer in a gloss charcoal finish.
